Resumo

Doente do sexo masculino, 9 anos, transplantado de medula óssea devido leucemia mielóide aguda, apresentou febre e tosse seca três dias após o procedimento. A radiografia de tórax demonstrou infiltrado reticular difuso bilateral. A tomografia computadorizada de alta resolução do tórax revelou espessamento do interstício peribroncovascular, pequenos nódulos centrolobulares periféricos e áreas de atenuação em vidro fosco. O lavado broncoalveolar demonstrou pesquisa positiva por imunofluorescência direta para anticorpos anti-vírus influenza B. Foi instituído tratamento com ribavirina aerolizada durante 10 dias com melhoria clínico-radiológica do quadro infeccioso.

Abstract

Nine year-old male patient, who underwent bone marrow transplantation because of acute myelogenous leukemia, presented with fever and dry cough three days after the procedure. The chest radiograph demonstrated bilateral diffuse reticular infiltrate. The high resolution computed tomography showed peribronchovascular interstitial thickening, peripheral small centrilobular nodules and areas of ground-glass attenuation. The bronchoalveolar lavage demonstrated positive direct fluorescence antibody testing against influenza B virus. Treatment with aerolizated ribavirin was instituted during 10 days and the patient showed clinical-radiological improvement.
